Background & Objective: The potent antioxidant property of fullerene C60 nanoparticles and their derivatives has been demonstrated in a wide range of in vitro and in vivo studies. Hence, we examined the effects of fullerene C60 on the oxidative stress parameters at brain and liver of rats in normal situation. Materials & Methods: The study was performed in two groups of Wistar rats (each group...

Rao, P. J. (University of Illinois, Urbana), A. D. Larson, and C. D. Cox. Catalase activity in Leptospira. J. Bacteriol. 88:1045-1048. 1964.-A number of serotypes of Leptospira were found to possess catalase activity, although considerable variation in activity existed among various serotypes. Catalase activity of L. pomona was reduced by inhibitors commonly employed for arresting catalase acti...

Type2 diabetes formerly known as non insulin dependent diabetes is the most common form of hyperglycemia, insulin resistance and relative insulin deficiency. The type 2 diabetes is caused due to metabolical disorder. Oxidative stress, through production of reactive oxygen species (ROS) to develop insulin resistance, beta cell dysfunction, impaired glucose tolerance there by impairing antioxidan...

It has been shown that the adverse effects of salinity can vary between different varieties same plant species. This study was conducted to determine tolerability three newly released lines maize saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic (SA) each at 1.0 M concentration; seeds distilled water were used as control. Concentrations 0, 50, 100, 150 30...

The formation of abnormal amino acid residues is a major source of spontaneous age-related protein damage in cells. The protein l-isoaspartyl methyltransferase (PIMT) combats protein misfolding resulting from l-isoaspartyl formation by catalyzing the conversion of abnormal l-isoaspartyl residues to their normal l-aspartyl forms. In this way, the PIMT repair enzyme system contributes to longevit...

Seed vigor is a complex property that determines the seed's potential for rapid uniform emergence and subsequent growth. However, the mechanism for change in seed vigor is poorly understood. The seeds of poplar (Populus × Canadensis Moench), which are short-lived, were stored at 30 °C and 75 ± 5% relative humidity for different periods of time (0-90 days) to obtain different vigor seeds (from 9...

Ischemia reperfusion injury (IR injury) is a common problem in clinical conditions. Researches have frequently revealed that ATP- sensitive potassium (KATP) channels and nitric oxide plays a role in protection against ischemic injury in skeletal muscle. The present study aimed at evaluating the possible link between this two pathways. Sixty-eight male wistar rats, were pretreated with saline, d...

objective: oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. the beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. this study was conducted to determine the effects of the hydro-alcoholic root extract of withania coagulans on ca1 hippocampus oxidative damages followin...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...
